About
Appalachian Series Day 3 takes place in Seneca, South Carolina, on March 21, 2027, as the third day of the Mainly Marathons Appalachian Series. Four distances are on offer on the day: the marathon (26.2 miles), the half marathon (13.1 miles), a 10K (6.2 miles), and a 5K (3.1 miles), so you can pick your effort according to how the series has treated you so far.
Multi-day series racing works on different rules from a single goal race. Nobody runs day three at personal-best pace; the aim is to finish upright and be able to start again tomorrow. Run a minute or two per mile slower than you would in a standalone race, walk the aid stations, eat more than feels necessary, and change socks between days. If you are dropping to the 10K or 5K on this day, treat it as an active recovery run rather than a chance to race.
